System and Method for Crowd-Sourcing Mobile Messaging Spam Detection and Defense

An apparatus comprising:

• a processor;
• and
• a memory to store computer program instructions, the computer program instructions when executed on the processor cause the processor to perform operations comprising:
• receiving a notification from a mobile device associated with a particular user identifying that a message received at the mobile device is determined to be an unwanted message based on:
• identification of the message as an unwanted message by an unwanted message detection algorithm;
• and
• the message being confirmed by the particular user to be an unwanted message;
• updating a copy of the unwanted message detection algorithm associated with the particular user, based on the notification to generate an updated unwanted message detection algorithm;
• transmitting the updated unwanted message detection algorithm to the mobile device associated with the particular user.

A computer readable medium storing computer program instructions, which, when executed on a processor, cause the processor to perform operations comprising:

• receiving, at a virtual machine associated with a particular user, a notification from a mobile device associated with the particular user identifying that a message received at the mobile device is determined to be an unwanted message based on:
• identification of the message as a potential unwanted message by an unwanted message detection algorithm;
• and
• the message being confirmed by the particular user to be an unwanted message;
• updating, at the virtual machine, a copy of the unwanted message detection algorithm associated with the particular user, based on the notification to generate an updated unwanted message detection algorithm;
• transmitting the updated unwanted message detection algorithm to the mobile device associated with the particular user.
